Answer:
A or D
Explanation:
Dd, dd would be their children's possible genotypes. Therefore, option (B) is correct.
The genotype of the first parent is Dd, which means they have one dominant allele (D) and one recessive allele (d). The genotype of the second parent is dd, which means they have two copies of the recessive allele (d).
When these two individuals have children, each parent will randomly pass on one of their two alleles to their offspring. Therefore, the possible genotypes of their children are:
Dd (with a 50% chance): the child inherits the dominant D allele from the Dd parent and the recessive d allele from the dd parent.
dd (with a 50% chance): the child inherits the recessive d allele from both parents.
Therefore, the correct option is (b) Dd, dd. The children cannot have a DD genotype because the second parent does not carry the dominant D allele.

The transport of molecules of a particular solute from inside an animal cell across the cell membrane to the extracellular fluid always requires energy when _____. View Available Hint(s) The transport of molecules of a particular solute from inside an animal cell across the cell membrane to the extracellular fluid always requires energy when _____. a transport protein is involved in the movement of the molecules the lipid bilayer is permeable to the solute the concentration of the solute is lower inside the cell than outside it the concentration of the solute is higher inside the cell than outside it
Answer:
the concentration of the solute is lower inside the cell than outside it
Explanation:
This question depicts the process of ACTIVE TRANSPORT, which is the movement of a substance against concentration gradient, hence, requires energy input (ATP) to occur. In this case, transporting a solute from inside an animal cell to the extracellular fluid across the cell membrane always requires energy.
This is because the concentration of solute inside the cell is much lower than that of the extracellular fluid, hence, to move the solutes against this concentration gradient (low to high), energy in form of ATP is required.
On the Indonesian island of Bali, about 3/4 of the feral (stray) cats have a stumpy tail while only 1/4 of the cats have a regular long tail. When you did some experiments and picked out a bunch of random stumpy-tailed cats and mated them, they had some stumpy-tailed kittens and some regular-tailed kittens. You did the same with the the regular tailed cats, but they always had only regular tailed kittens. What does this tell you about the genotype of the regular tailed cats
Answer:
That stumpy tail is the dominant trait, while the regular long tail is the recessive trait.

what trait only appears when a organism is a homzygous
Answer:
Both can show.
Explanation:
The genotype can look like the following:
TT <= Homzygous Dominant
tt <= Homzyogous Recessive
Tt <= Heterzygous
See? It would be hard to determine exactly which trait would show without the second half of the name! (By the way, I can't say the proper names so I apologize)

Does DNA undergoes translation to produce proteins . RNA undergoes mutation to produce cell walls
Answer:
No
2. Yes
Explanation:
This is because DNA undergo transcription to produce RNA and RNA undergo translation to produce protein. Translation is the process where mRNA molecule is used as a template to produce protein.
RNA undergo mutation more than DNA and this is because the enzymes found in RNA viruses and participate in copying viral genomes is why it occur so. These enzymes does not have the abilities to recognize DNA damage that enzymes in most organisms have.

Explain why when the DNA is being replicated during the S phase of the cell cycle, it copies each strand differently.
Answer: Each strand act as a template strand for another strand this way two strands are responsible for the production of two new strands. This way after the replication process two DNA molecules are produced.
Explanation:
S phase of the cell cycle is the synthesis phase of the cell cycle. This phase occurs after the interphase of the cell cycle. In this phase, the replication and synthesis of the DNA occur. The genetic material gets copied and doubled in this process before it enters into mitosis or meiosis. Each strand is utilized as a template strand for the synthesis of the complementary strand this way two molecules of DNA are produced. This way each cell contains a diploid set of chromosomes before it undergoes cell division into daughter cells in mitosis or meiosis.
Each strand act as a template strand for some other strand this manner strand is accountable for the manufacturing of new strands. In this manner after the replication system DNA molecules are produced.
S phase of the cell cycle is the synthesis section of the cell cycle. This section happens after the interphase of the cell cycle. In this section, the replication and synthesis of the DNA arise. The genetic material receives copied and doubled on molecular this system earlier than it enters into mitosis or meiosis.
Each strand is applied as a template strand for the synthesis of the complementary strand this manner molecules of DNA are produced. In this manner, every cell carries a diploid set of chromosomes earlier than it undergoes cell department into daughter cells in mitosis or meiosis.
What is the S phase?S phase (Synthesis Phase) is the section of the cell cycle wherein DNA is replicated, taking place among the G1 phase and G2 phase. Since correct duplication of the genome is essential to a successful cellular department, the techniques that arise for the duration of the S-phase are tightly regulated and broadly conserved.
Hence it states that the DNA is being replicated during the S phase of the cell cycle, it copies each strand differently.

How do both sodium and potassium ions travel
Answer:
Sodium ions pass through channels in the hydrophobic barrier that have been formed by membrane proteins. The crossing membrane is called facilitated diffusion because it is facilitated by the channel
Potassium ions have to be transocated through specific membrane transport proteins. It is then transported into the cell through potassium pumps with energy being consumed int the form of ATP.
The sodium-potassium pump goes through cycles of shape changes to help maintain a negative membrane potential. In each cycle, three sodium ions exit the cell, while two potassium ions enter the cell. These ions travel against the concentration gradient, so this process requires ATP.
Explanation:
Answer:
The sodium potassium pump goes through cycles of shape changes . In this way they help maintain a negative membrane potential. In each cycle, two potassium ions enter the cell while three sodium ions exit the cell . These ions travel against the concentration gradient. And this process requires ATP.

The stars appear to move across the sky every day, but
their paths change throughout the year. Here is a model of
the Sun-Earth system.
Based on the model, which three factors might cause this change in the
apparent movements of the stars?
Answer:
Earth's Revolution around the sun, The tilt of Earth's Axis, and Earth's rotation on its axis.
Explanation:
I have done this test
1. The Earth's revolution around the Sun: As the Earth revolves around the Sun, the stars appear to move across the sky each day. This is because the Earth is rotating on its axis, which causes the stars to appear to be moving from east to west.
2. The Earth's tilt: The tilt of the Earth's axis also has an effect on the apparent movement of the stars. As the Earth rotates around the Sun, the tilt of the Earth's axis changes throughout the year. This causes the stars to appear to move slightly differently at different times of the year.
3. The Precession of the Equinoxes: The precession of the equinoxes is the gradual wobble of the Earth's axis which takes place over thousands of years. This has an effect on the apparent movement of the stars, as the angle of the Earth's axis changes over time. This causes the stars to appear to move in a slightly different pattern than they did thousands of years ago.
